A novel method that uses bacteria to mine valuable minerals from the ocean has been developed. Nodules collected from the Indian Ocean seabed can be treated to extract scarce land-based minerals in an environmentally sound way, says research published in the Journal of Chemical Technology and Biotechnology.

Using the marine species Bacillus M1, Cobalt, Copper and Nickel can be extracted from the nodules at a near neutral pH and room temperature. In a single four-hour process, 45% Cobalt and

At present, we know of no worlds beyond our Earth where life exists. However, primitive organisms on our planet have evolved and adapted over billions of years, colonising the most inhospitable places.

Since life seems to gain a foothold in the most hostile environments, it seems distinctly possible that living organisms could exist in ice-covered oceans on worlds far from the Sun, according to Dr. David Rothery (Open University), who will be speaking today at the RAS National Astronomy Mee

If Washington state issues additional permits for water to be diverted from the Columbia River for farm irrigation, it should do so only under the condition that withdrawals can be stopped if river flows become critically low for endangered and threatened salmon, says a new report from the National Academies’ National Research Council. Salmon are at increased risk during periods of low flows and high water temperatures, conditions that are most likely to occur during the summer months when deman

Chemists at Ohio State University and their colleagues may have settled a 70-year-old scientific debate on the fundamental nature of ice.

A new statistical analysis mechanical theory has confirmed what some scientists only suspected before: that under the right conditions, molecules of water can freeze together in just the right way to form a perfect crystal. And once frozen, that ice can be manipulated by electric fields in the same way that magnets respond to magnetic fields.

When the European Huygens probe on the Cassini space mission parachutes down through the opaque smoggy atmosphere of Saturn’s moon Titan early next year, it may find itself splashing into a sea of liquid hydrocarbons. In what is probably the first piece of “extraterrestrial oceanography” ever carried out, Dr Nadeem Ghafoor of Surrey Satellite Technology and Professor John Zarnecki of the Open University, with Drs Meric Srokecz and Peter Challenor of the Southampton Oceanography Centre, calculate

Emissions from ships may bring as much nitrogen oxide to the atmosphere as the total amount of emissions coming from the USA. International shipping along the Norwegian coast and in the Northern Atlantic Ocean contributes largely to the formation of ground-level ozone and acidification of the shores.

Air pollution from ships may be twice as bad as shown by previous estimates. In high traffic areas emissions may affect the climate just as much or even more than other forms of emissions. This
